Fish typically release nutrients at the same depth at which they feed. Excretion for marine mammals, tethered to the surface for respiration, is expected to be shallower in the water column than where they feed.</p>", "links"=>[], "tags"=>["conceptual"], "article_id"=>495331, "categories"=>["Ecology", "Marine Biology", "Inorganic Chemistry"], "users"=>["Joe Roman", "James J.
